number assignment is determined by the functional group
the lowest number will be assigned to a carbon nearest the functional group
(or substituent)

5’ and 3’ strands of DNA
directionality - of the single strand DNA where the nucleic acid are
chemically oriented
5’ and 3’ strands of DNA
directionality - of the single strand DNA where the nucleic acid are

5’ and 3’ strands of DNA
the nucleic acid structure
5’ and 3’ strands of DNA
the direction of the strand is determined by the chemical orientation
of the nucleic acid
5’ and 3’ strands of DNA
deoxyribonucleic acid
5’ and 3’ strands of DNA
5’ and 3’ strands of DNA
the blue strand is assigned as 5’-end
because the phosphate group covalently bonded to the backbone is
attached to Carbon #5
5’ and 3’ strands of DNA
the red strand is assigned as 3’-end
because the phosphate group covalently bonded to the backbone is
attached to Carbon #3
the Bases
Nitrogen-containing compounds have basic properties
Base pairing
Base pairing (DNA)
number of hydrogen bonds between bases
Base pairing (RNA)
number of hydrogen bonds between bases
